Also Motorola.

Can't forget Motorola, who's original company name was Galvin Manufacturing Company, their original line of business was to manufacture radios for cars, hence the name "Motor-ola". Then they got into portable radio equipment like for taxi cabs, and cop cars, then they developed the Handi Talky during the war. Unfortunately they were bought by Poohgle, who really knew nothing about manufacturing hardware, so they broke it up and sold off parts of Motorola to some Korean and Chinese purveyors of junk electronics, except for those parts the U.S government forbade them to sell for security reasons.
